` To 'all whom "it `amy concern: g.

` 1Beit -lrn'oiin tl'iatjl, CiLiRLns S. CHRIS NAN, a cit'izeiifof the United States, and a resident oit' Nest Chester, in the county of Chester and State :of Pennsylvania, have invented a certain neiv anduseiul Oil-Inliector (for vVVatenGas Apparatus and the like, of ivhichthe following' is a specification. i y

` 'lhepriricipal objects of tliepresent inven-` tion arefirst" to provide torminsuring the protection ,0"1` `oil nozzles used intermittently ttorfiilijcctingfoil iiitoa lieatedregion from the` deleterious erliects of heat when the oil is turned off, ,andsecon`d, to provide for pro-k l v jecti'ngand retracting an yoil nozzle inauto" matic and contemporaneous response to the' control otitheoil supply and in respect to a regionfof heat that Would "be injurious 'to nozzle `is certainly suppliedivith oil When propelled into `a heated region',` such `asfthe interior of the carburetor fof a Water gas set, and is retracted Lfrom thehe'ated "region when andas the' oilsup'ply is out oil" or discontinii'ed.,l v

` The io'reooine ob'ects and others whichy b 12D f, i

will hereafter appearr in this description are accomplished `by mechanismyor means of which embodiments are selected for the sake' of explanation and illustration in the acconifpanying drawings inwhichI lthe invention", and

as by acyliifider-liead 6, provided With hany, dles f?, f 12, is la connection communicating i with the Acylinder near its closedl end and provided `with valves '13 and 13a, the `former `for 'oil and the latter for ysteam which may be used for purging purposes. 9 and 11, are

valve elements interconnected, for a limited range 'of' relative kmovement into pistonforining position as shown and, into fluid-` `Way forming position. The valve element 9,

"is tubular andis provided With an internal( valve seat :formed on the ring 10, which in 1` i iS-pecication'of Letters Patent. Patntd Aug', 21, 1917, Aptiiationeiedoctgter11,1916. seriai'nofizaizi.

use isrgidly connected With the element 9. The other valve element 11, Consists of a dish-valve confined in the tubular valve element so as' to cooperate with the internal valve seat and to bemovable in respect to the element 9. 8, is an oil nozzle connected sov as to communicate With the interior of the valve element 9. As shown this is accomplishedby the pipe 16, .connected with the element 9, and Withfthe nozzle. The valveelement 11, kisconnected by a rod 3, with a Weighted lever mechanism arranged ati the'closed end `of thef cylinder 1. This Weighted mechanism is shown to comprise Weigh-ted arms 5, pivotally: connected With the rod 3, and 'i'vithilinks 4, and which in turn arepivoted to the lugs 7. The Weighted lever Vmechanism therefore acts upon `the rod 3,111 a straight line. 15, is a base tov which the cylinder is connected by a prolongation'of the cylinder-'or sleeve let.

lt may be assumed that cz, is the top Wall of the carbureter of ak Water gas set because oil is sprayed into the carbureter intermit tently and because the temperature of the interior of a carbureter is such that itivould deleteriously affect thevnozzleS, if the` latter Were not supplied ,With oil and was per mitted to project into said chamber. y.In the absence of oil, the Weighted lever mechanism operates to put the valve elements 9 and 11,

e into position for forming a piston and vto drai'v them toivardthe closed end of the cylf inder, thus retracting `the nozzle yS, outof Vhen oil is,

the heated zone or region. admittedto the cylinder 1, as by opening the valve 13, the pressure of the oil overcomes the actionof the Weightedy lever mechanism and theoil drives the elements'Q andll, in piston-forming position outward, thus projectingy the nozzle 8. At the end of this outward ystroke. the valve element 9, abuts CHARLES, oiinrsivrAN, or' Wnsfr CHESTER. PENNSYLVANIA, AssIGNoR 'ro THEJUNI'TED PHILADELPHLA, PENNSYLVANIA,` A CORPORA- upon the 'stop 2, and thefvalve .element 11,V p

clears its seat so that theoil passing through the tubular' valve element 9, past thedisk-` valve element 11, reaches the nozzle'S, as it` arrives in its projected position and so the oil flowing through the nozzleprotects `it from the deleterious effect of heat. When the valve 18, is closed there is `no longer hyA `,drostatic pressure in the cylinder and Whatever oil may be contained in the cylinder in leaking out past the valve 117 permits the weighted lever.A .mechanism to ,retractv the nozzle 8, and partsconnected therewithto their initial position before the lapse of suiiicienttime for causing injury to the noz- Zle` VS, by exposure to heat without a supplyv of oil. A pin-'hole 11a, may be provided in order to insure suiiicient leakage and when present it is too smallto interfere with the described piston action on the outward stroke.vv When steam is introduced by opening the valve 13a, the operation ofV the parts is as above described. i

From the foregoing description it is evidentv that at the end of the outward stroke of `the "piston the'ynozzleis projected and a port or by-pass is opened in order to supply the nozzle with luid'trom the'cylinder. In

Fig.; 2, this result is also accomplished 'and` the yconstructioi'i and arrangement' of vthe modiiicationshown yin that igureare they sainefas shown in Fig. 1, except that a spring 5&is illustrated instead of the equivalent weights, andthe piston 17, is constructed as a unitary structure, or of:l parts relatively im.` movable' in` operation, and use is made of a port or ports 18, adaptedfto form in connection with aypassage 19, in the piston a hyp-pass Aaroui'id the piston only when in its outward position.

will be obvious to those skilled in the art to which the inventionrelates that modiications may be made in details of construction and yarrangement without. departing from the spirit of theinvention so that the latter is not limited as to those matters or in any way further than the prior state ofthe art; and the appended claims mayre'quire.: j `What I claimis:y I 1.` An oily injector for' .water gas apparatus l r and the like comprising thecombination of a cylinder closed at `one end and having ka e valved inlet, retractingmechanism, a piston element operatively connected'lwith theretracting'mechanism, a nozzle connected with the piston element and projected and retracted thereby, and by-pass provisions from the cylinder' to the nozzle yand opened by the outward and, closed by the inward stroke lot the piston,substantially as described., v
